Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
mRNA (multicoloured strand) is decoded in a ribosome to produce an aminoacid chain, that folds into a protein (red). tRNA (dark violet) molecules carry single aminoacids that are incoporated into the growing chain.

Immunotherapy of Alzheimer's disease: Monoclonal antibody (light blue) bound to an amyloid beta peptide (orange),  that is aggregated to amyloid beta fibrils, which build up amyloid plaques.
DNA A-T Pair
Biological protein and molecule, 3d rendering. 3D illustration.
A ball and stick model of Eicosapentaenoic Acid or EPA. It is an omega-3 polyunsaturated fatty acid. It is introduced into the diet by eating oily fish. When it comes to fat, there’s one type you don’t want to cut back on: omega-3 fatty acids. Two crucial ones - EPA and DHA - are primarily found in certain fish.
Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering

3D cartoon and Gaussian surface models. PDB 2aai, white background.
Abstract shape with particles on blue background. Digitally generated image.
DNA methylation is the main epigenetic modfication of DNA. Methylation (white spot) can change the activity of a DNA segment. The DNA methyl transferase I (light blue) transfers a methyl group from S-adenosyl methionine  (red) mostly to cytosine bases of the human DNA. Source: PDB entry 3pt6
